ELECTRONICALLY CONTROLLED REGULATOR

Abstract: an electronically controlled regulator may include a pressure regulating valve, which may include a discharge pressure regulating unit that adjusts a pressure of a fluid by changing a distance between a valve body and a valve seat while reciprocating a valve shaft by a valve shaft moving structure using a feed screw, a slidable piston that receives a fluid pressure in a discharge pressure chamber, and a spring that constantly biases the valve shaft in a valve closing direction. at the time of valve closing, the fluid pressure received by the piston may be converted into a pressure load in a direction of pressing the valve body, and at a time of pressure adjustment, a positional deviation of the valve shaft due to a backlash provided at a meshing portion of the feed screw may be avoided by a biasing force of the spring.
